Jacob Steven Leach: trading record in brief
Filings by Jacob Steven Leach span 2 companies, the busiest being Dexcom Inc and SenesTech, Inc. The record holds 26 filings, for trades running from 9 June 2021 to 22 August 2026.
In open-market terms, that means 2 purchases worth €813k on one side and 11 sales worth €20.3M on the other. Taken together, the sales exceed the purchases by €19.5M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 11 share grants.
The newest entry dates from 25 August 2026: a share grant of €115k, in Dexcom Inc. The last insider purchase was made public on 10 November 2025, 342 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
